The common species is adult at five inches. That depends on temperature, pH, hardness, and food. Buy six, and you have a 70 percent chance of at least one pair.
That's up to the knowledge of the novice as to the species in question. With proper research first, yes, a novice could have bristlenose breed in their tank.
